Greenhouse Gas Emissions

To better understand our environmental impact and increase the transparency of our operations, we have voluntarily tracked and reported our greenhouse gas (GHG) emissions since 2009.

While we are proud of the fuel efficiency improvements we have made in recent years, we continue to seek opportunities to further reduce our emissions intensity. In 2019, we continued to support efforts to advance the sustainable aviation fuel industry. Red Rock Biofuels began construction of their refinery in 2018, and we have committed to purchase three million gallons of sustainable aviation fuel per year from them when it becomes available.

The commitment to purchase lower carbon renewable fuel is just one way we are striving to reduce our emissions intensity.

Southwest has committed to purchase three million gallons of sustainable aviation fuel per year from Red Rock Biofuels, when it becomes available.
